Darwin's finches by John Gould. A rooted phylogenetic tree see two graphics at top is a directed tree with a unique node — the root — corresponding to the usually imputed most recent common ancestor of all the entities at the leaves of the tree. A rooted bifurcating tree has exactly two descendants arising from each interior node that is, it forms a binary tree , and an unrooted bifurcating tree takes the form of an unrooted binary tree , a free tree with exactly three neighbors at each internal node. CS1 maint: Over a century later, evolutionary biologists still use tree diagrams to depict evolution because such diagrams effectively convey the concept that speciation occurs through the adaptive and semi random splitting of lineages.
